Ravi has 6 sweets. He wants to share them equally with his friend. He gives 3 to his friend and keeps 3. They both get the same! When we can share a number equally into two groups with nothing left over, it is an even number. If there is one left over, it is an odd number.
Even Numbers
Even numbers can be divided into two equal groups. They always end in 0, 2, 4, 6, or 8.
Even numbers up to 20:
2, 4, 6, 8, 10, 12, 14, 16, 18, 20 Example: 8 sweets shared between 2 friends = 4 each. No sweets left over. So 8 is even.
Odd Numbers
Odd numbers cannot be divided into two equal groups. They always end in 1, 3, 5, 7, or 9.
Odd numbers up to 20:
1, 3, 5, 7, 9, 11, 13, 15, 17, 19 Example: 7 sweets shared between 2 friends = 3 each, with 1 left over. So 7 is odd.
Quick trick: Look at the last digit. If it is 0, 2, 4, 6, or 8 -- the number is even. If it is 1, 3, 5, 7, or 9 -- the number is odd.
